The defence team for Huawei executive Meng Wanzhou has filed a notice of civil claim alleging ``serious violations'' of her constitutional rights.

The suit filed with the B.C. Supreme Court on Friday is against members of the Canadian Border Services Agency, the RCMP and the federal government.

It seeks damages for false imprisonment based on alleged multiple failures of government officials to comply with the rule of law upon her detention, search and interrogation at the Vancouver airport on Dec. 1.

The allegations have not been proven in court and the CBSA, RCMP and the attorney general's office did not immediately respond to requests for comment.

On Friday, the Canadian Department of Justice gave the go-ahead for an extradition case against Meng, marking the formal start of the high-profile process that has put Canada in an uncomfortable position between the United States and China.

The U.S. Department of Justice has laid out 13 criminal counts of conspiracy, fraud and obstruction against Huawei and Meng, who is the daughter of company founder Ren Zhengfei.
